この問題は次のバージョンのcfgで修正される予定です．

こちらは，cfg1_out のsrcに./arch/arm_m_armcc/common/start.sx を登録し
て，コンパイル対象に入れてもらえると解決します．

start.sx 登録後は，start.sx のOption -> Properties でFile Type をC
Source file にしてください．

次回のリリースで修正します．

こちらも，次回のリリースで修正します．

ARMCCのalignディレクティブは，ARM命令の場合は，2^nでアライメントするのに
対して，Thumb2命令の場合は1*nでアライメントするのが原因でした．次のリ
リースでは，ご指摘の通りに修正します．

以上，よろしくお願いします．
